Thank you for writing about this.  I added support for the DViCO 
Bluebird devices, and I am also experiencing the same issue when using 
the driver under 2.6.16 ...  The device is able to recover when you 
remove and re-insert the module, or if you disconnect and reconnect the 
device, but that isn't practical, considering that you are probably 
relying on the box to work in order to record HD programs.

I have spoken to Patrick about this, and he tells me that the same bug 
exists in other dvb-usb devices, and also flexcop-usb boxes.  I don't 
have a flexcop-usb device to test with, but I do have some ideas as to 
how to prevent this from happening on the FusionHDTV boxes.

I hope to have some time within the next two weeks to work on 
alleviating this issue.  The past few weeks have been quite busy for me, 
but I will keep your email address handy and I'll let you know when I 
have a fix that you can test.

In the meantime, some good news:  The remote control is working for this 
box, and support has been added to 2.6.17-rc1 ...  You can update your 
driver by following the instructions here:


Thanks again for reporting the bug -- it is a known issue, and it helps 
to hear someone else (besides me) complain about it.  I'll let you know 
as soon as I am able to chase this down.
